Oxford Industries

(OXM) - Get Report


Shares plunged 21.2% to $28.55 after the Atlanta-based company said its continuing-operations income

slid 57.2% year over year to $4.8 million, or 27 cents a share, in the quarter ended Aug. 31. Sales were off 16.2% to $237.9 million. Analysts polled by Thomson Financial had sought 46 cents a share, minus extraordinary items, on a top line of $247.3 million.

The Children's Place

(PLCE) - Get Report

, a children's clothing retailer, said its fiscal third-quarter EPS should be

at least 60% under the 94-cent low end of prior guidance -- that is, some 38 cents or below, including a 7-cent charge for severance payments to former CEO Ezra Dabah. Analysts are looking for 97 cents a share before special items. Fourth-quarter and full-year earnings should also come in "significantly below" prior expectations.

The Secaucus, N.J., outfit blamed too-high inventory levels paired with poor revenue trends -- including about a 3% drop in September same-store sales -- which forced "a substantial amount of unplanned markdowns." Children's Place stock surrendered $1.52, or 6.3%, to $22.80.

Implant Sciences

( IMX), of Wakefield, Mass., said it shipped six units of its Quantum Sniffer BTS Benchtop Explosives Detection System to its Chinese distributor for delivery to the Beijing police, who are expected to use the products for security and antiterrorism measures during the 2008 Olympics.
